Dear experts,

I think I need to send you the information of my ROI,i am not sure whether it is something wrong.

This is the part of the 4gt.label I drew.And the attachment is the picture of the 4gt.label. Thanks again.

Sure.This is the full terminal output:

Can you send the full terminal output?

External Email - Use Caution Hi Bruce, I drawed a 3D ROI on the original image using freeview,and saved it as an label file. Then I wanted to sample it to my subject and to found the closest surface vertices so that I can extract the cortical thickness of ROI. I used the command line: mri_label2label --srclabel 4gt.label --s PT1_4 --trglabel 4reg.on-pial.label --hemi rh --paint 30 pial --trgsurf pial. But it reported error: Line 3:4445 Segmentation fault(core dumped), mri_label2label.bin "$@". Can you tell me how to solve this problem?Is it wrong to use the mri_label2label? Thanks. Best wishes， Kan Deng
